It's possible you have a client on your network attempting to access a
mis-configured web server farm. Normally requests would go to a front-door
server and get NAT'd back to another set of servers to actually handle the
request. For some reason, the responses from these servers are not getting
NAT'd back to the original source address so they appear as spurious packets
from a private address space on port 80.

ZoneAlarm reported this burst, all from port 80 on a reserved IP
block. What the honk's going on?
